Enable best settings for Photographs in Firefox

Friends you all know I am great fan of the Mozilla Web browser Firefox. Along with tech and Linux Digital Photography is also something that makes my heart flutter :) Here is a quick guide to enable optimal setting in your Firefox for displaying the best looking photos.

Go to address bar type about:config  and press enter.. now in the search bar type gfx.color
press enter. You should see the following entries with there default values.

gfx.color_management.enablev4   ----- false

gfx.color_management.mode    ------- 2

gfx.color_management.rendering_intent ------ 0

gfx.color_management.display_profile ----- blank

Now before we go on tweaking the settings make sure that you are set to use Color management at the OS level. I use Fedora Linux with KDE 4.10.x which has system wide color management enable.
For Windows look under Control Panel > Color management. Make sure the OS load the correct ICC profile for the monitor that you have.

You can also use the model specific tool for this.. for e.g my Samsung SyncMaster came with software to load the correct monitor profile and color setting tools. Check you vendor web site for updates or patches for your model. Now once we have a color profiled monitor and OS ...

Toggle gfx.color_management.enablev4   --- True.

Possible values and their effects

False    (default) Version 4 is not enabled
True    Version 4 is enabled

gfx.color_management.rendering_intent   change to    -1

Possible values and their effects

Honor the rendering intent specified in the image file.


Relative colorimetric

2    Saturation

3   Absolute colorimetric

gfx.color_management.mode  change to

Possible values and their effects

0   Disable color management.
1   Enable color management for rendered graphics.
2  Enable color management for tagged graphics only. (Default)

"Value 0" equals "Color management disabled" — This means different things depending on the Operating System:

OS-X, Windows: RGB 'numbers' are passed straight to the monitor unchanged. 

"Value 1" equals "Full color management" — This means everything tagged is Converted to Monitor RGB, and everything untagged is Assigned sRGB and then Converted to Monitor RGB.

"Value 2" equals "Color management applied only to tagged images" — This means Tagged files are Converted to Monitor RGB and untagged RGB is sent straight to the monitor unchanged.

That's all it that simple to have better Photographs in Firefox, restart the web browser. If you find all this manual editing a bit of hassle use the "Color Management" add-on to do the same. Have fun :)
